mediate tibiae ending in two long spines nearly as long as the apical 

 spurs, posterior ones broadly dilated at apex and deeply scooped 

 inwardly, the spurs are robust and compressed in both sexes, and 

 blunt at apex in the female, both tibiae are strongly uni-carinate 

 outwardly, and the tarsi are short and numerously bristly under- 

 neath ; mesosternum extremely small, not excavate, mesothoracic 

 episterna very large ; metasternum sending a small, bluntly triangular 

 process between the median coxae. 



This genus seems to be restricted to the Karrooid fauna. It 

 comprises two species which will prove probably to be coprophagous, 

 as I found them alive, and also dead in or near cattle kraals. They 

 fly at night. They may, however, prove also to be living in the 

 heaps of excrements of termitaria. That they are burrowing insects 

 is well proven by their very robust legs and powerful hind spurs. 



Key to the Species. 



Black, with a very broad, reddish-brown band along tbe outer 

 margin of tbe prothorax ; anterior part of prothorax witb a small 

 elevation in both sexes sanguinipes. 



Black; anterior part of prothorax excavate or not in the <? , but 



always witb a distinct tubercle comuta.

Piceous- black on the upper side but with the sides of the 

 prothorax and occasionally the centre sanguineous ; under side and 

 legs chestnut-red or chestnut-brown, but occasionally the whole 

 body is quite black ; the head is also sometimes rufescent ; antennae 

 rufescent ; clypeus deeply sinuate in front in both sexes, sparsely 

 punctate like the head, which is clothed with a not very dense 

 fulvous pubescence ; prothorax very little convex, ampliated laterally 

 from the apex to the rounded outer part of the base, glabrous on the 

 upper side hut having a fringe of rufo-fulvous bristly hairs along 

 the outer margin and also a few setulose ones in the supra-marginal 

 punctures, the anterior margin has a small, tubercle-like prominence 

 in the centre in both sexes ; the surface is deeply punctate, the 

 punctures are more numerous and much more scabrose on the sides; 

 scutellum very long, very sharp at apex, deeply punctate, each 

 puncture bearing a small, fulvous hair; elytra elongated, slightly 

 narrowed behind, plane or nearly so, with the humeral callus not 

 strongly pronounced, there are on each side two sub-sinuate 

 discoidal costules reaching the hind callus, and the suture is
